CONVERTIBLE BED.

Application filed January This invention relates to certain improvements in convertible beds. The main object of the invention is the production of a bed structure that ordinarily takes the form of a. couch or single-bed, but is readily convertible into a double bed when desired, both sections of the bed in the converted form resting independent of the other solidly upon the Hoor, but equipped with c0- operating parts causing the elevation of one of said sections when the structure is re-con verted into single bed form so that it no longer rests upon the iioor, but is carried and supported by the other section.

Other objects and advantages relate to the details of the structure. all as will more fully appear from the following description, taken in connection with the accompanying drawings, in which Figure 1 is a perspective view of a convertible bed of our invention.

Figure 2 is a section on line 2 2, Figure 1.

Figure 3 is a perspective view partially in section at one corner of the bed illustrating the means for normally preventing separation of the bed sections.

Figure 4 is a section on line 4 4, Figure 1.

Figure 5 is a section similar to Figure 4 with the structure in double bed form.

'The convertible bed of this invention primarily consists of a main 'frame -1- of rectangular form and consisting of preferably a rectangular angle iron framework of proper size to constitute a single bed 'and supported at its four corners by the corner-posts -2-, -3--, -4- and -5-. The cornerposts -2- and -3- are preferably connected by a head-rail -6-, while the corner posts 4.- and 5 are connected by foot-rail -7-, and the corner posts -3- and 4- are connected by a back-rail --8.-. these rails may be of anydesire'd form, and of any ornamentation, and may, if desired, as

l shown, constitute the two sides and back of a couch. The front posts -2- and -5- are connected solely through thev medium of the front section of the angle iron frame! 2o, 1925. 'serial No. 3,569.

perhaps best illustrated in Figure 4, consists of two similar connected sections, one adapted to be folded upon the other when the strueture is used as a single bed.

The structure so far described constitutes an ordinary single bed except for the provision of the couch-like rails -6-, 7 and -8- before described.

In addition to the single bed structure described, this convertible bed includes al second rigid rectangular framework *1lof substantially the same size and form as the main rigid rectangular frame-work 1--. This second rigid framework for the purpose of this application is termed an auxiliary rigid rectangular framework, and as here il lustrated, is of slightly greater width than the main framework 1- and its rear portion is adapted to move beneath the rear rail -8- as best illustrated in Figure 4, and this enlargement in width is desirable in order that theframework -11- may be adapted to receive within it a third rigid rectangular framework -12- here termed a supplemental rigid rectangular frame.

And this supplemental frame is of substantially the same size and form as the main frame -1, altho perhaps of slightly less width and slightly less length, to permit its reception within the framework -11- and the positioning of the latter framework below and insubstantial registration with the main framework 1 -.The supplemental framework l2- carries a series of springs 1S-- constituting a spring-bed and adapted t0 be used in conjunction with one section of the mattress .-10- when the latter is unfolded as best illustrated in Figure 5.

Normally when the structure is utilized as a couch or single bed the supplemental framework -12- is collapsible withinthe framework -11-, as illustrated in Figure 4. When, however, the structure is utilized as a double bed, as illustrated in Fig. 5, the supplemental framework -12-.- is elevated to the level of the main framework -1- by means of head and foot lever mechanisms --14-,. These mechanisms are of identical construction, and each comprises a pair of oppositely disposed levers 15 carried by the rock-bar -16- mounted in the oppositely disposed longitudinal angle-iron of the frame -11-. These two levers -15- are conneeted by cross-bars -17- and 1S- upon the upper one of which the frame -12- no1.- mally rests. The front one of the levers is formed with an extension -19- constituting a handle by means of which the lever structures can be rocked so that they lie in the framework #1l-- as illustrated in Figure 2 when the frame -12- is collapsedwithin the frame wil" or can be moved to a sub'- stanti ally vertical position to thereby elevate the framework -12- to the level of the l framework -1-- as illustrated in Figure 5.

This particular elevating means constitutes no portion of the present invention.

The special novel features of the present construction will now be described. At each of the rear corners ofthe main frame -l at the corner posts f3- and 1l-, there is provided a comparatively short inclined track section -20. These track sections may be formed of angle irons with their vertical sides secured to the respective posts 3 and 4- and the respective head and foot rails -6- and -7- as illustrated here by three screws or bolts -2land the other angle of the angle iron 20 inclines upwardly from the horizontal as it extends rearwardly, for a purpose hereinafter described.

Each front corner of the main frame at the posts 2- and respectively is provided with a second comparatively short track sec tion 22W- which may also be formed of angle iron having its vertical wall connected to the posts 2 and 5- respectively and the .luead and foot rails -6 and -7- respectively in any suitable manner, as by screws -23-. These track sections -22 are further provided with downwardly bent 0r formed portions 2LP- lying below the hori-y zontal size of the angle irons constituting the track`\ sections Q2- And as suggested, these track sections -22- have their side wall which constitutes their track portion substantially horizontal. v

The auxiliary frame -11 is adapted dur ing practicallyV all of its movement to and from a position beneath the main frame -lto move on and be supported by its own legs 44.- provided with castors -25- and preferably these legs are supported at four respectlve points adjacent the four corners of the frame 11- by means of brace-bars -26- which extend from one angle iron to the other at the four corners of the bed, and as illustrated form triangles withl the adjacent portions of the angle irons so that the supporting castors are within the frame -11-. ,L The angle irons at the head and foot of the frame -1l are formed as best illustrated in Figures 4 and 5 with downwardly pressed or counter-sunk portions -27- which lie slightly below the remaining portions of the angle irons, and below the lower plane of the framework --11-, and each of these head and foot angle-irons at'the rear of or adjacent the rear of its depressed portion -27- is formed with a dog -28- which `may be formed by slitting the angle-iron and vfollowing lVhen the frame 12-` is collapsed within the frame -lland the frame -11- resting upon its castors '-Q5-d is pushed rearwardly under the main frame -'1, it will, until it approaches the limit of its rearward movement, move upon its own castors upon the ioor which independently supports both it and the main framework. l/Vhen the rear rail of the framework -12- approaches the limit of its rearward movement, it will move over the lower forward end -29 of the track section -20--and further rearward movement will cause a slight elevation of the rear side of the framework l1- suflicient to lift the castor *Q- from Contact with the supporting floor.

qAt the same time the depressed portion -27- of the head and foot angle iron sections of the framework -11- will be brought into contact with the horizontal portion of the tracks -22 and the forward portion of the framework -llwill be elevated a distance suflicient to raise the front castors -25 from contact with the supporting floor and 'at this point the supplemental framework is supported entirely on and beneath the single bed structure, including the main framework. When the limit of rearward movement has been reached Where the front board #SO- contacts with the main framework 1, the dog -28- will drop against and at the rear of the horizontal portion of track section -22-` and will under normal circumstances prevent separation of.

the supplemental framework from the single bed structure. When it is desired to effect such separation, it is only necessary to lift the forward portion of the framework -11- as by means of the front board 30 so as to free the dog 28- from engagement with the rear end of track section 22- when the framework -11- may be freely withdrawn, and after movement of a few inches will rest and roll vupon its supporting castors Q5- .[he front board -30- as shown, is carried by the front longitudinal angle-iron of frame -11- and is preferably of a width so as to extend above the main frame -1- and slightly overlap the mattress l0- so as to produce a finished structure iny single-bed form. A

,It is found desirable to normally limit the outward movement of the framework -11- in the course of producing a double bedin order to prevent separation of the sections, and for this purpose the rear longitudinal angle iron of the framework -11- is formed with a latch -31 having one end pivotally connected to the angle iron as by rivet or bolt S2- and its other end lying below the head or foot section respectively of the framework -11- so as to come into contact with the flange -24- on the track -22- when the framc -11- has been drawn out from beneath the frame -1 to the desired position for forming a double bed. i

As suggested, the rear longitudinal rail of the framework -11- at both the head and foot of the bed is formed witha latch -31.

One of these latches may be rigidly secured to the angle iron as by rivet B2-- or series of rivets. One of them however, should be secured to the angle iron in a movable manner so as to permit it to be moved to a position where it will not engage the flange Q4- should it be desirable to separate the frame -11- from the frame -1 and for this purpose as best shown in Figure 3, in ad- `olition to the pivotal bolt -32- a second removable connection is shown to normally prevent pivotal movement in the form of a removable bolt -33- normally held in place by a Cotter-pin, as illustrated.

It will be obvious from the above that there is here illustrated a structure capable of use as either a single or a double bed, both sections of which during motion of their relative movement are supported independently of each other lupon the ioor, but during a small portion of their movement and while the two sections are in registration one beneath the other, the one is supported on and by the other independently of the ioor so as to' produce a singlebed structure of a unitary character, and adapted for joint movement by the mere movement of the single bed structurel including the main frame, and altho Wehave shown and described a specific structure as illustrative of an embodiment of our invention, we do not desire to restrict ourselves to the details of the structure or the parts thereof, as various changes may be made within the scope of the appended claim.

We claim:

The combination with a single bed structure having a spring-supporting frame, of a collapsible single bed structure capable in collapsed condition of being moved underneath said spring-supporting frame, and inclined guides at the .rear side of the single bed'
